SPECIFICATION forming To all whom it may concern:

Be it known that I, GEORGE E. BRADLEY, a citizen of the United States,residing at Atlanta, in the county of Fulton, State of 5 Georgia, haveinvented a new and useful Improvement in Seed-Cotton Cleaners, of whichthe following is a specification.

My invention relates to improvements in seed-cotton cleaners, thecleaning being ae- IO complished by the suction of all impurities fromthe cotton after it has been sut'ticiently agitated, the broad principleof which of course I admit to be old.

The objects of my improvement are to supply to the market a machine moresimple in construction, cheaper, and better adapted to general use thanall other machines for the same purpose involving any ora likeprinciple. I attain these objects by the mechanism illustrated in theaccompanying drawings, in

Which- Figure 1 represents a perspective View of the entire machine,while Fig. 2 represents a vertical section of the same.

Similar lettersrefer to similar parts throughout the several views.

A A represent the standards, which support the whole machine.

B represents the hopper into whieh the cotton is deposited for cleaning.The bottom of this hopper is composed of slats, with intervening spacesfor the escape of dust and other impurities that fall from the cottonwhile in the hopper and in the process of being fed to 5 5 the cleaner.

0 is the opening through which the cotton is passed into thebeating'chamber D. This chamber, with its smooth inner surface, is linedwith sheet-iron or other suitable mate- 0 rial, save a small space inthe center of the upper and lower part of said chamber, which smallspaces d d (the latter thus forming a part of the inner surface of thebeating-chamher) are made of net-work, to allow the cscape of all dust,trash, and other impurities from the chamber after their separation fromthe cotton. Within thischamber, and upon the only shaft used in thisdevice, is a hub, E, with of the fan chamber.

part of Letters Patent No. 255,486, dated March 28, 1882.Applicationfiled January 20, 1882. (Model.) I I and deposits saidimpurities part into a sand box, G, and the remainder is caused to passout through a flue, H, at the bottom and rear of the fan-chamber. I

The fan-arms b &c., are constructed of iron or other suitable materialafter the manner of the heaters, save the addition of the'fan-leaves b bto the former. In the side of this fanchamber are valves J'J, throughwhich air is admitted, and which serve to increase or dimin- .ish thedraft at pleasure, and thus facilitate the regulation of the dischargeof the cotton. On ordinary occasions, and when the cotton is dry, thevalves may he closed; but when the cotton is damp, resisting by itsheaviness expulsion, the valves may be opened and the cotton easilyexpelled from the beating chamber. The cotton is discharged from thebeatingchamber through an aperture, 1, in the front of said chamber, andnear the opening 0, through which the cotton passes into this chamber.

The operation of this device is as follows: The cotton, after being putinto the hopper, passes from the same into the heating-chain ber, whereit is beaten and knocked to pieces by the heaters, while through thewire portion at and the detachable cap 0 immediately above there isallowed to pass air for the Yen til-ation and the cleaning of thecotton, after I which the air is drawn from this ehamberinto thefan-chamber, while the dust, sand, and other impurities pass with it andare discharged into the sand-box and out at rear flue The smooth innersurface of the beating-chamber does not catch and destroy the fiber ofthe cotton while it is substantially as described, and for thepurunizlergoing the whipping operation. poses set forth.
